Dhanush

The Dhanush Stabilised Launch and Fire Control System has been designed, developed and realised by L&T, jointly with DRDO. The system comprises an electro-hydraulic stabilised weapon platform for launch of Dhanush Missile from the deck of Naval Platforms, and an Object Handling System for the transfer of missiles from storage hangar to the stabilised weapon.

The Dhanush Fire Control System, used for preparing and launching the Dhanush Missile, accepts target positions over a radio link from the Central Command. Redundant processors compute the missile trajectory and also give corrections for the positions and roll-pitch angle of the ship.

The firing solution comprises sequential preparation of missile, by checking sub-systems and sensors, loading firing solution, transfer alignment of missile INS, command and authority checks and finally the launch cycle. FCS also provides mechanisms for auto-detection of launch failure/ hang-fire and secures the missile for safe handling thereafter. The Fire Control System is based on Vx Works RTOS and Hardware based on VME architecture.

BrahMos

L&T in collaboration with DRDO has successfully developed, manufactured and delivered Vertical and Inclined Launcher Modules for the Brahmos Missile System for the Naval Platforms. The Fire Control System for the naval platform is completely designed, developed and manufactured by L&T. The Universal Vertical Launch Module (UVLM) system is a modular launch system for canisterised BrahMos missiles on board ships and controlled by a Fire Control System (FCS) which has been developed in-house.

L&T has also manufactured and installed the Inclined Launchers for the BrahMos Missile. The BrahMos Fire Control System is capable of simultaneously controlling 2 to 32 missiles in single or salvo mode. It accepts target data from a Radar or CMS and calculates the missile trajectory. Major functions of this FCS include Missile Preparation, Missile Health Check, Hit Probability Calculation and Cartographic Display. This is also interfaced with MINS for information on platform position and dynamics.
